Said frame is ofa hollow cylindrical formationand ldepends'from `the connecting troughsection 25.

."Ihe. cylindrical .frame 24v.-is..secured7to .the-60 Lunderside vof theconnectingtrough r section- 25 and; as herein shown, .has an .integrally yformed i ireinforcing.- pla-tefl 6l extending. .therefrom along the undersideY of said connecting troughssection VArand secured-tthereto. :vu-.Said .connecting trough?` V55 section is secured at its forward end to the driven trough section I3 by means of connecting bolts 21, 2T extending through .aligned eye pieces 28, 28 in adjacent ends of said trough sections.

The shoe I9, as herein shown, is circular in form having an upturned periphery to permit ease in sliding movement along the ground, and has an upwardly extending hollow. cylindrical central portion 34. Said hollow cylindrical portion is adapted to be engaged by the inner periphery of the depending walls of the hollow cylindrical frame 24, thus forming a pivotal and slidable connection between said frame and said upwardly extending central portion of said shoe.

The means for vertically adjusting the frame 24 with respect to the shoe I9 includes a threaded shaft 35 secured at its upper end to a boss 36 disposed centrally of the cylindrical wall portion of said frame. The depending end of said threaded Shaft is threaded within a threaded member 3l disposed centrally of the cylindrical portion 34, and herein shown as being formed integral therewith. A handle 39 is secured to the shoe I9 and projects outwardly therefrom. This handle is adapted toV receive the end of a pipe (not shown) or any other means for obtaining a mechanical advantage for turning said shoe and thus elevating the frame 24 Yand the connecting trough sections 20 and 25 with respect to the ground in an obvious manner.

It will be seen from the foregoing that a simple form of swivel has been provided for connecting two portions of a shaker conveyer trough line together and permitting one to swivel with respect to the other in a horizontal plane, which swivel is so arranged as to aiord vertical ladjustment of adjacent ends of these sections of the pan line and thus permit one trough section to be disposed along a ledge above the mine bottom and gather mined material therefrom. It will also be seen that the means for affording vertical adjustment of the trough sections is of a simple and compact form so arranged that rotation of the supporting shoe for the swivel causes vertical movement of the trough sections with respect thereto.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction thereof and the arrangement of the various parts may be altered without departing from the spirit and scope thereof. Furthermore, I do not wish to be construed as limiting myself to the specic embodiment illustrated, excepting as it may be limited in the appended claims.
